GEORGE A. OVER-BECK, OF GLENFIELD, NORTH DAKOTA.

STALL FLOOR.

Application filed February 27, 1922.

T 0 all whom it may concern:

Be it known that I, GEORGE A. OVERBECK, a citizen of the United States, residing at Glenfield, in the county of Foster and State of North Dakota, have invented certain new and useful Improvements in Stall Floors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such. as will enable others skilled in the art to which it appcrtains to make and use the same.

' The present invention relates to stall floors, and aims to provide means whereby the floor of a stall or floors of several stalls can be elevated and dumped or tilted to discharging position for the convenient cleaning of the floors.

Another object is the provision of novel means for mounting a stall floor for upward and downward movement and for dumping or tilting movement when raised, and means for elevating the floor.

A further object is the provision of novel means for retaining the floor in horizontal position when raised and lowered, and operable for enabling the floor to swing to dumping or inclined position when elevated, and limiting such turning or dumping movement.

lVith the foregoing and other objects in view, which will be understood as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope or what is claimed, without departing from the spirit of the invention.

The invention is illustrated in theaccompanying drawings, wherein- Figure 1 is an end view of a pair of stalls.

2 is a fragmentary side elevation of one stall floor in lowered position, portions being broken away.

Fig. 3 is a side elevation showing the floor elevated and in dumping position.

Fig. 1 is a plan view showing the adjacent edge portions of the two floors and the intermediate partition.

Fig. 5 is a fragmentary side elevation showing a modification.

The floors 10 of the stalls are made of wood or other suitablev material, and are of suitable size, according to the stalls in which the floors are used, and said floors normally seat on the base or foundation between the partitions or walls 11 of the stalls.

Serial No. 539,666.

Each floor has pivots or trunnions 12 at its side edges between the ends thereof engaging slides 18 which are movable vertically in the slideways or grooves formed by pairs of vertical strips or cleats 14 fastened to the partitions or walls 11. The slides 13 are thus guided for vertical movement, for the upward and downward movement of the floor, and the floor being pivoted or :tulcrumed to the slides, can be swung about a transverse axis.

In order to elevate the floors of the several stalls simultaneously, a cable or chain 15 is provided, and passes over the pulleys 16, 17 and 18 carried by the partitions or walls near the ceiling, and the cable has a return run 19 extending from the pulley 18 under the pulley 17, and over pulleys 20 and 21 disposed at the opposite sides of the respective partitions to which the pulleys 17 and 16 are fastened. The run 19 terminates in a terminal 22 extending downwardly from the pulley 21 and connected to the corresponding slide 13. A branch terminal 23 is secured to the run 19 and passes over the pulley 20 and is connected to the corresponding slide 13. Branch terminals 2 1 and 25 are connected to the cable 15 above the run 19 and pass over the pulleys 18 and 17, respectively. and are connected to the corresponding slides, whereby when the cable 15 is pulled, the floors are elevated, as seen in Fig. 1. The terminals of the cable are sufficiently long to permit the floors to be lowered onto the base or foundation, as will be understood.

As shown, the cable 15 is pulled by draft animals, the cable extending under a pulley 26 fastened. near the floor below the pulley 16, and a doubletree 27 is attached to the tree terminal of the cable for hitching one or more draft animals to the cable, whereby it can be pulled to raise the floors. Abracket 28 is secured above the pulley 26 and has a pivoted cam 29 thereon with a handle 30, for clamping the cable 15 when it is pulled to raise the floors, thereby supporting the floors in elevated positionuntil the cam or clamp is loosened to enable the cable 15 to be pulled back by the gravitation of the floors.

In order to hold each floor horizontal while being raised and lowered, and to enable the floor to be moved to and retained in dumping position. a bar 31 is pivoted between its ends, as at 32, to one edge of the floor between the rear end of the floor and the corresponding pivot 12, with the rear end of the bar 31 terminating short or spaced from said pivot. A brace link 33 is pivoted at one end to the rear end of the bar 31 and at its other end to the corresponding slide 13 above the pivot 12. When the bar 31 is swung to a position'to extend along the edge of the floor, the floor will be in horizon tal position, and the rear end of the bar 31 is fastened to the floor by suitable means, such as a slidable latch 34: on the rear end of the floor to engage the rear terminal of the bar. The brace link 33 is therefore in inclined position between the slide 18 and the bar 31 which is prevented from swinging relatively to the floor by the latch 34.

VVhenth floors are raised, they are therefore retained in horizontalposition, and the floors can then be dumped and cleaned oii one at a time. By retracting the latch 3a of a floor, the corresponding bar 31 is released, thereby permitting it to swing relatively to the iioor, and the rear end of the floor can therefore swing downwardly to bring the floor to discharging or dumping position, as seen in Fig. 3, in order that the iloor can be conveniently cleaned oil. The link 33 and bar 31 straightenout, as seen in Fig. 3, to limit the downward movement of the rear end of the floor, and therefore support the floor in proper inclined or tilted position, and enabling a wheel barrow,

wagon or other receptable to be positioned below the rear end of the floor to catch the matter dumped from the floor. By raising the rear end of the floor to horizontal position, the bar 81 is swung to a position along theedge of the floor, and said bar can then be latched to retain the floor in horizontal position. The other or next floor can then be dumped in the same way, and returned to horizontal position. lVhen the several floors have beencleaned ofi, the cam or clamp 29 can be released, to enable the floors to be lowered. Inthis way the cleaning ofi of the floors is made convenient and easy.

The terminals of the cable or lifting means are preferably detachably connected to the slides, such as by means of hooks 35 to which said terminals are connected to detachably engage the slides. Thus, should one of the animals be sick, so that it cannot be taken from the stall, the corresponding hooks 35 can be detached from the slides 13 of such stall, permitting the remaining floor or floors to be raised. This permits of any of the floors being disconnected from the hoisting means. i

It is also preferable to fasten a transverse bar 36 of stout metal across the bottom of each floor 10 between the pivots 12, whereby to prevent the floor from sagging between. the slides 13 when the floor is raised.

As shown in Fig. 5, the floor 10 can have an offset, as at 37, whereby the rear end aces portion of the floor is lower down than the forward portion, such as used for cattle stalls. J

Having thus described the inventmn, what is claimed as new is 7 1. An animal stall having a loose floor,- vertically movable slides at the sides of the stall to which the side edges of the floor are pivoted for the elevation of the floor with the slides and the tilting movement of the floor to dumping position, and means arranged along one side edge of the floor and connecting the floor and corresponding slide for supporting the floor in substantially horizontal position when elevated and adapted to be released to permit the floor to move to dumping position.

2. An animal stall having a loose floor, vertically movable slides to which the floor is pivoted to be elevated with the slides and to tilt to dumping position, pivotally connected members pivoted to the floor and one slide and arranged, when straightened out, to limit the movement of the floor when tilted to dumping position, and means for holding said members in a predetermined position to support the floor in a substan tially horizontal position.

3. A stall having a loose floor, vertically movable slides to which the floor is pivoted to be elevated with the slides and to tilt to dumping position, a bar pivoted to the floor between the ends of the bar and between the rear end of the floor and the slides, a brace link connecting one slide and the for ward end of said bar, said bar and link limiting the swinging movement of the floor when tilted to dumping position, said bar extending along one edge of the floor when the floor is in horizontal position, and means for latching the bar to the floor at the rear end of the floor.

4. A stall having a loose floor, vertically movable slides to which the floor is pivoted to be elevated with the slides and to tilt to dumping position, and means between the floor and one slide for supporting the floor in substantially horizontal position and including a controlling member carried by the floor at the rear end thereof operable for releasing the floor for tilting movement.

5. A stall having a loose floor, vertically movable slides at the sides of the stall to which the floor is pivoted to be elevated with the slides and to tilt to dumping position, and means connecting the floor and one slide for supporting the floor in substantially horizontal position when elevated. said means being located at one side edge Of the floor and bei g arranged to he released at the rear end of the floor to permit the floor to tilt to dumping position.

6. A floor. vertically movable slides to which the iioor is pivoted, a bar pivoted to :the floor, a brace link connecting said bar and one slide, and means for latching the bar to the floor whereby the bar and link retain the floor in horizontal position, and said bar and link limiting the swinging movement ,of the floor when the bar is unlatched. s

7. A stall having a loose floor, means for mounting the floor for vertical movementand for tilting movement to dumping position, and means for supporting the floor in substantially horizontal position when elevated and having a controlling member carried by the floor at the rear end thereof to permit the floor to be released for dumping movement.

In testimony whereof I have signed my name to this specification in the presence of tWo subscribing, Witnesses.
